A decoder includes memory and a processor coupled to the memory and configured to: generate a first coefficient value by applying a CCALF (cross component adaptive loop filtering) process to a first reconstructed image sample of a luma component; clip the first coefficient value such that the clipped first coefficient value is within a first range from −27 to 27−1; generate a second coefficient value by applying an ALF (adaptive loop filtering) process to a second reconstructed image sample of a chroma component; clip the second coefficient value such that the clipped second coefficient value is within a second range different from the first range; generate a third coefficient value by adding the clipped first coefficient value to the clipped second coefficient value; and generate a third reconstructed image sample of the chroma component using the third coefficient value.
An encoder comprising:
An encoding method comprising:
A non-transitory computer readable medium storing a bitstream, the bitstream comprising clip information according to which a decoder performs a CCALF (cross component adaptive loop filtering) process and an ALF (adaptive loop filtering) process on a first reconstructed image sample of a luma component and a second reconstructed image sample of a chroma component, respectively,
